| 英文摘要 | a series of half-salen ligands and their aluminum al(iii) complexes that contained different substituents were designed and synthesized. all the ligands and their complexes were characterized by h-1, c-13 nmr and elemental analysis. the complexes can be used as catalysts to produce polylactide and poly-epsilon-caprolactone. all polymerizations were living with narrow molar mass distributions. the m-n(obsd) values of the isolated polymers were in good agreement with m-n(calcd). the polymerization rate of the electrophilic substituted complex was higher than the non-electrophilic substituted analogues. the more bulky substituents with more steric hindrance of the complexes showed relatively low polymerizing activity. the aluminum complexes showed a moderate stereo-selectivity to the ring opening polymerization of raclactide to give isotactic enriched polylactide. |
